3 Claims.

ent invention is to provide a bearing mounting' in which the locking collar and hence the inner bearing member remain firmly secured to the shaft.

The invention consists principally in a locking collar for such constructions, wherein sufficient flexibility is provided in said collar at its point of engagement with said bearing member to Aaccommodate flexing of the shaft and other misalining movement of the bearing member. The invention further consists in providing a resilient sleeve or insert in the portion of said locking collar that overlaps and engages the bearing 25 member. The invention further consists in the bearing mounting and in the parts and combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawing:

Fig. 1 is'a longitudinal sectional view of a pillow block having a bearing mounting embodying my invention,

Fig. 2 is a cross-sectional view on vthe line 2.2 in Fig. 1; and

Fig. 3 is a partial longitudinal of a modification.

In the drawing is illustrated a pillow block including a shaft I, 'a double row cone 2 or inner bearing member thereon, a housing 3, bearing 40 cups Il in said housing, taper bearing rollers 5 between the cups and the respective raceways 'of said bearing cone and locking collarsfor said bearing cone indicated generally by 6.

Each locking collar 6 comprises an annular 45 lbody portion I provided with threaded holes 8 in which are mounted set'screws 9 that' engage the shaft I and a projecting sleeve portion I0 that extends into the housing 3 and overlaps a cylindrical portion II on the end of said bearing 50 cone 2. Mounted in the end portion of each sleeve I0 is aring I2 of rubber or other resilient material in which is a ring I3 o r sleeve of metal, the rubber ring I2 being preferably vulcanized both to the inside of said projecting sleeve lil of 35 sectional view i938, Serial No. 227,081

(SUE. 287-52) l said collar and to the outside of said metal sleeve I3. Each metal sleeve I3 fits closely on a projecting end portion II of said bearing cone.

Preferably the bore I4 of said bearing cone 2 is suiiciently larger than the outside diameter of the shaft I to provide clearance between the two members, the bearing cone being supported solely in said metal sleeve i3 of said collars 6.

In the modiedoconstruction shown in Fig. 3,

the projecting ends 30 of the bearing cone are tapered and the metal sleeve @I has a conical bore to `fit thereon. In this construction the cone is shown as fitting on the shaft in the usual way.

The rubber insert i2 in said collar accommodatesany slight movement or misalinement, due izo-flexing ofthe shaft or other causes and thus largely relieves the set screws of strain that would cause them to loosen, resulting in loosening of the bearing member.

Obviously, numerous changes may be made without departing from the invention and I do not wish to be limited to the precise construction shown.

What I claim is: l

1. A roller bearing mounting or the' like comprising a shaft, an annular member thereon having a projecting end portion and a locking collar secured to said shaft, said collar having a portion overlapping said end portion of said annular member, a resilient ring in said overlapping portion of said collar, and a metal ring within said' resilient ring and engaging said end portion of said annular member.

2. A roller bearing mounting or the like comprising a shaft, an annular member thereon having a tapered end portion and a locking collar secured to said shaft, said collar having a portion overlapping s'aid end portion of said annular member, a resilient ring in said overlapping p0rtionl of said collar, and an internally conical metal ring withinsaid resilient ring fitting said tapered end portion of said annular member.

3. A roller bearing mounting or the like comprising a shaft, an annular member thereonhaving a projecting end portion and a locking collar secured to said shaft, said collar having a portion overlapping said end portion of said annular member, a rubber ring in said overlapped portion of said collar, and a metal ring within said resilient ring andengaging said end portion of said annular member, said rubber 'ring being vulcanized to said collar and to said metal ring.
